Algebraic Expressions


• Variable-– Is a letter or symbol that represents a number that

can change • Constant- – Is a quantity that does not change

• Algebraic Expressions– Contains one or more variables and may contain

operation symbols

One Step Equations

• Equation- – Is a mathematical statement with two equal

quantities. (Contains an equals sign)• Solutions – The answer to an equations

• Equivalent Expressions: Expressions that simplify to an equal value when numbers are substituted for the variables of the expression.

• Addition Property of Equality: Adding the same number to each side of an equation produces an equivalent expression.

• Subtraction Property of Equality: States that when both sides of an equation have the same number subtracted from them, the remaining expressions are still equal.

• Multiplication Property of Equality: States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal.

• Division Property of Equality: States that when both sides of an equation are divided by the same number, the remaining expressions are still equal.
